Qrispy eSIM does not provide an unlimited data eSIM for Belgium. All of its Belgium plans are Pay‑as‑you‑go data credits, with the largest option offering roughly 10GB of data at the current local rate. The credit does not expire, so any unused data remains available for future use, and additional credit can be purchased whenever needed.
Because the plans are Pay‑as‑you‑go, travelers only pay for the data they actually use and can top up as their consumption grows. This model can be more cost‑effective than a fixed unlimited plan for most users, especially those who do not consume data at a very high volume.
